I'm looking to replace my recoil springs on my Baer TRS and it's the first time having done so, just reaching the 2500 round mark. I'd like to order a few to stock up, but what should I get. I heard Wolff were good, but I'm confused on variable vs. conventional or load-rated springs. I shoot strictly 230 grain FMJ or JHP. I'm going with 18.5# but variable or conventional??
I run a 14# conventional (or "straight") spring in my 5" 1911 in .45 ACP. The reason so light? The more the recoil spring "weighs" the more muzzle flip you will get. Reducing the spring weight will reduce the amount. However, that doesn't mean you get crazy and run REALLY low rates (for instance on my Open pistol I run a 9# and my Limited pistol carries a 12#).
The "correct" spring for me is based on reliability and then feel. Try a couple out, see what works the gun best, then what feels right. As long as the spring doesn't compress past it's full compression (i.e. "slams" into the frame) during cycling, it won't damage anything. And, let's face it....springs are cheap.
